The Soundtracker


FOREWORDS: the trackers are typical affordable (or free) musical sequencers used by various system.

The concept was born in 1987 with the ULTIMATE SOUNDTRACKER (EAS Computer Technik) written by Karsten Obarski for the computer Commodore Amiga using the 4 PCM samples voices generated by PAULA audio chip.

editWhat's a MUSIC TRACKER? the original tracker was based on simple sequencers using internal samples (not Midi samplers). Each samples was entered as a note (pitch samples) into different channels lined up on columns patterns. The samples can be usually edited (eg.volume and EG for early trackers) depending on the software, then the song can be saved on various "module" format like .mod, IT, S3M [...]



editMUSIC TRACKER Influence right after the Ultimate Sountracker release, many freeware / shareware "clones" appeared and music trackers began to be appreciated amongst DEMO SCENE people, not to mention some commercial blockbuster games.
The tracker concept is born with the Amiga, but evolved and spread on both modern platforms (e.g PC RENOISE) and even older computers (C64, spectrum, MSX, Atari). Today tracker softwares handle much more tracks, feature high quality samples, sound filtering, VST effects, virtual instruments and much more.

editThe tracker sound collection ST-XX in order to reduce file dimension and simplify songs swaps, many modules did not include the most common samples since these were on available on free sound library collections called "ST-" followed by a number indicating the disk number (officially from ST-01 to ST-116).
Most of these samples were recorded from synthesizers or drum machines from this era, but seldom reported the original recorded source but some short "hints" (e.g.heaven-> staccato heaven). The first disk ST-01 was probably the most popular and used as it contains some very classic sound you heard hundreds of time on classic Amiga songs. According to some web indications, I managed to record some original synth sound sources - not an easy task since Amga ST-01 short samples were recorded at 8/11 kHz at low 8 bits resolutions with many audio artefacts.

Here's a full 44 kHz 24 bits STEREO recording from original machines, this will be updated when new sounds (for suggestions drop me a LINE).




edit ST-01 SAMPLES FROM ROLAND D50 a classic digital synthesizer from 1987 based on LA synthesis, well-known to retrogamers for the Roland MT32 module.

edit ST-01 SAMPLES FROM YAMAHA DX-TX 4OP line many samples come also from FM synthesizers developed by Yamaha. The 4 operators family are compatible between them and read the same sounds, so it is actually impossible to tell the specific original module or synthesizer.
- 4OP with standard sinewave: DX21 - DX27 - DX100
- 4OP with sinewave + harmonic variations: TX81Z - DX11.
Later models (V50- TQ5 - WT11 - YS100/200) could no be as the ULTIMATE SOUNDTRACKER has been released in 1987.
According to the ST-01 likeness names, it is probable that the sound sets comes from DX21 presets.
HINT: FM synthesis has been also implemented on famous PC soundcards ADLIB/SOUNDBLASTER with the OPL chip.
